Rota™ Red Folding Knife Sharpener

I was skeptical about the folding design, but it locks solidly in place and the non-slip feet keep it steady on the counter. The coarse wheel took care of my dullest chef's knife in a few passes, and it folds flat enough to toss in a drawer.

The twin ceramic wheels really do the job—course side first, then fine, and my dullest kitchen knife glides through tomatoes again. The non-slip feet kept it steady on the counter, and it folds flat enough to tuck beside the cutting board.

Folded up it takes almost no drawer space, yet the twin ceramic wheels go from coarse to fine in one spin. The non-slip feet kept it steady even when I pressed down hard on a dull blade. This thing made my old kitchen knife scary sharp again in under a minute.
